Your product for Quaternary Treatment

The all-in-one product for CLEAN WATER.

Welcome to the future of wastewater treatment! We are setting new standards for clean water with our all-in-one product - DONAU PAC® AQUACLEAR.

The particular strength of DONAU PAC® AQUACLEAR lies in the removal of micropollutants (e.g. pharmaceuticals, cosmetics, pesticides and other chemicals) and chemical phosphate precipitation - all without additional equipment or structural measures. This pioneering technology offers maximum effectiveness with very low investment costs and clearly calculable operating costs.

The outstanding effectiveness of DONAU PAC® AQUACLEAR has been scientifically tested and confirmed by renowned, independent institutions such as the Vienna University of Technology. DONAU PAC® AQUACLEAR has been successfully in use since 2021.
